Canadian Superior Updates Status on "Victory" Well Offshore Trinidad

CALGARY, ALBERTA--(Marketwire - Sept. 25, 2007) - Canadian Superior Energy Inc. ("Canadian Superior") (TSX:SNG)(AMEX:SNG) announced today that its "Victory" well is currently drilling on the "Intrepid" Block 5(c) offshore Trinidad at a depth of 12,285 feet subsea.

The "Victory" well had previously reached a total depth 16,621 feet (subsea), and was evaluated while drilling with Measurement While Drilling (MWD) and Logging While Drilling (LWD) data (gamma, electrical resistivity, cutting samples, gas in mud measurements, drilling parameters). However, while attempting to come out of the hole to commence wireline logging and possibly flow testing of the well, difficulties were encountered which resulted in being unable to remove the full drillstring from the well. Accordingly, the drillstring was severed at a depth of approximately 11,726 feet and the well plugged back to a depth of approximately 9,594 feet, as announced on September 11, 2007.

The lower portion of the well is being re-drilled to a projected total depth of approximately 16,000 feet and is being directionally drilled approximately 400 feet from the original wellbore to attempt to ensure the new wellbore is not affected by drilling muds and fluids lost from the original wellbore. Upon reaching total depth, open hole wireline logging and other tests of the wellbore will be completed.

The "Victory" well was spudded the well on June 29th and due to operational delays beyond the control of Canadian Superior and its partners, wireline logging operations related to the well are now expected to be completed by October 15, 2007.

Canadian Superior's joint venture partners in the "Intrepid" Block 5(c) Project are BG International Limited, a wholly owned subsidiary of the BG Group plc (LSE:BG.L), who is paying 40% for a 30% working interest and Challenger Energy Corp. ("Challenger") (TSX VENTURE:CHQ)(AMEX:CHQ), who is paying 33-1/3% for a 25% working interest, resulting in Canadian Superior is paying 26-2/3% of the exploration program cost to maintain a 45% working interest in the Block. The Kan Tan IV semi-submersible drilling rig, operated by Maersk Contractors, is drilling the "Victory" well and is also contracted to drill two additional back-to-back wells on Block 5(c), named "Bounty" and Endeavour".
